cullAttributes() Method Mutates Props Directly

[giorgosart]

In the EasyEdit component, the cullAttributes() function directly mutates the attributes object from props:

cullAttributes() {
  const { attributes } = this.props;
  delete attributes["type"];
  delete attributes["onChange"];
  delete attributes["value"];
}

Props should be treated as immutable in React, and mutating them directly can cause unexpected side effects, especially when attributes are passed by reference or reused.
